Excerpt from On Germinal Transplantation in Vertebrates The curiosity of zoologists has long been aroused to know whether the reproductive gland of a vertebrate can be successfully transplanted from the body of one individual to another; and, if so, whether the gland will thereafter function in its new environment; and, if it does, whether the nature of its products will remain unaltered. The fact has repeatedly been pointed out that experiments of this sort, if successful, Should afford a crucial test of the Lamarckian and the Weismannian views, respectively, of the relation of the germinal substance to its environment and in particular to the body.

The global triumph of Mendelian genetics in the twentieth century was not a foregone conclusion, thanks to the existence of graft hybrids. These chimeral plants and animals are created by grafting tissue from one organism to another with the goal of passing the newly hybridized genetic material on to their offspring. But prevailing genetic theory insisted that heredity was confined to the sex cells and there was no inheritance of characteristics acquired during an organism’s lifetime. Under sustained attacks from geneticists, scientific belief in the existence of graft hybrids slowly began to decline. Yet ordinary horticulturalists and breeders continued to believe in the power of grafting. Matthew Holmes tells the story of these organisms—which include multicolored chickens and black nightshades that grew tomatoes—and their enduring influence on twentieth-century biology. Their creators sought a goal as ambitious as the wildest dreams of genetic engineering today: to smash the barriers between species and freely exchange genes between organisms. The Graft Hybrid presents a greater understanding of the controversial history of graft hybrids, offering a crucial intervention in the history of genetics and the future of biological science.

"Sengoopta shows that Weininger's misogynist and anti-Semitic views did not stem solely from his private prejudices but were part of a comprehensive (and quite typically Viennese) analysis of masculinity and femininity and a critique of modernity in general and of feminist activism in particular."--BOOK JACKET.

An outcome of the 1930 series of Lane Medical Lectures at Stanford University. To develop the completed personality a long series of interactions between the original basis and the surrounding environment is essential. A discussion of the effects on developing personalities of uniting entire individuals and of transplanting organs and parts leads to a convincing demonstration of the "high improbability of the inheritance of acquired characters." From the chapter on exaggerated deviations from racial types, in which the author treats of dwarfs and giants, we are led into a section on deviations in structural types among various breeds of dogs. The closing chapters treat mainly of the two normal adult types, the dolichocephalic (linear, long-headed) and the brachycephalic (lateral, short-headed), their characteristics, geographic distribution and age modifications. A brief section is devoted to the sex glands, senility and rejuvenation, the author demonstrating that the sex gland rejuvenation idea is based upon an entirely erroneous conception. Man's deviation from his nearest animal relatives, namely, intellectual achievement, has probably been initiated by two evolutionary changes: (1) some mutation which has resulted in the retention of head proportions comparable to those found in the fetal stages of the higher mammals: this gives a disproportionately large cranium and big brain with small facial region as compared to the reverse adult proportions among other mammals; (2) a germinal mutation resulting in an exaggerated prolongation of childhood and the stages of immaturity to more than twenty years, thus extending enormously the learning period of man. There are considerable experimental material, over seventy figures, and a bibliography of 260 titles.

First published in 1925, “Animal Genetics” is a vintage treatise on breeding animals, including fowl, sheep, pig, dog, horses, and cattle. Animal breeding is a branch of animal science that deals with evaluating the genetic value of livestock. The ability to select animals with superior EBV in growth rate, meat, milk, egg, or wool production has revolutionised livestock farming around the world, and this handy volume aims to present the livestock keeper with everything they might need to know. With a wealth of invaluable information and many handy tips, Animal Genetics” is not to be missed by those with a practical interest in breeding animals for profit or pleasure. Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction on farming.
